Greenhouse Frame Choices

The structure that holds the glazing in place

Wood:
Wood is moderately priced, but deteriorates over time, especially at the point of contact with the ground.

It requires some maintenance and it blocks part of the light.

As a woodworking hobbyist, it saddens me to say that wood won't cut it for the IDEAL greenhouse frame.

Steel:
This is solid, long-lasting and heavy.

It is quite workable, albeit a bit heavy for my taste. Steel is best for big (i.e. commercial sized) structures.

Because of its weight, I would have to say steel isn't the best choice for normal sized greenhouses.

Aluminum:
This is an excellent choice -- light weight, long lasting, easy to work with.

It has a narrow cross section to let in the maximum amount of light for best plant growth.

I’ll take it.
